BIOLOGY 9 Lecture Notes - Lecture 3: East Los Angeles College, Limiting Factor, Hydrogen Bond
Document Summary
Law of limiting factors: any factor outside the optimal range will cause stress and limit growth, reproduction, and survival of a population. Limiting factors may be a problem of too much or too little. They can change over time (e. g. , temperature vs. nutrients) The ultimate limiting factor: an organism"s genetic potential. Synergistic effects (synergisms): factors (e. g. , pollution) that interact to cause a greater effect than expected. Habitat: the place defined by the plant community and physical environment where a species is adapted to live. Niche: the sum of all conditions and resources under which a species can live. What the animal eats, where it feeds and lives, how it responds to abiotic factors. Species coexist in an area but have separate niches. Organisms take in matter and energy from the environment to grow and function. Matter: anything that occupy space and has mass. Atmosphere: the thin layer of gases separating earth from outer space.
